Looking to buy a 09+ AC pre runner. I need the 6 foot bed and I like the looks of the AC better than the DC (long bed DC looks a little funky to me). Anyway, I dont plan on having people sit in the back of the AC but i noticed the flip down seats on the 09 look a little more friendly for people than the 05-08 bench. Anyone know if the 09 flip downs are somewhat comfortable for average sized adults to sit if need be? Also, if I were to purchase a 05-08 AC pre runner, is it possible to swap out the bench seats for the 09+ flip downs/buckets? Thanks.

I don't think they're interchangeable. The floor and seat are basically one. I've never had to ride in the back of my truck but nobody has complained yet. I never go far when somebody is in the back. I think the 05-08 seat is more cargo friendly too.
